Rename entryPoints to injects.

This is closer to what we actually do. It's a type that can be
injected. There's a slight bit of ambiguity because we use 'inject'
to describe types that are included implicitly. I don't anticipate
this to be a problem in practice.

Rename entryPoints to injects.
Remove the need for jekyll.
Migrate website to the new hotness.
Fix validation when passing an interface to the injects list.

I admit that this fix is clumsy. The core problem is that
the 'injects' list serves double duty: it includes types that
we can call ObjectGraph.get() on (could be interfaces) and also
types that we call ObjectGraph.inject() on (can't be interfaces).

The right fix is to rethink the way Dagger internally tracks
and links these keys.

Add two Android examples.

Simple example showing how to integrate Dagger and Android as well as a more complete example showing per-Activity graphs.

Since Travis CI hates Android we explicitly disable the modules being compiled in the build config.

Use two dollar signs between class name and dagger-generated suffix.

This prevents the extremely rare (but possible) case where a generated class for a type has naming conflicts with a static inner class on that same type.
